WATER-GAGE.

` SPCIFICATION forming part of Letters Patent No. 278,223, dated May 22, 1883.

" Application filed March 13, lPel. (No model.)

attached to the end of a boiler or to a planel vertical wall. Fig. 2 is a side elevation ofthe device when attached to a curved wall. Fig. 3 is a longitudinal section of the upper connecting-tube and a portion of the gage-tube. Fig. 4 is a vertical section on the line y g/,Fg.3.

In the drawings, A represents a portion of a steam-boiler sufcient to illustrate the method of applying my improved gage thereto. The

2o boiler is tapped or provided with a threaded aperture at a, and into this is fitted one part of the gage-support. This latter is constructed 1 of the tubular 'part B, an expanded sleeve or chamber, C, and a tubular extension, D. The part B is provided with a screw-thread, d, b vmeans of which it is joined tothe boiler, and with a valve-seat, b', at the outerend ot'the inner tubular passage, b2. InV the tubular projection D there is mounted a valve, E, the stem eof which engages with said tubular part D by a screw-thread at e', 'there being a handwheel at'e2,of the usual character. The valvestem is mounted across the sleeve or expanded chamber C, and bears directly against the valve-seat b.

The gage-tube is represented by F, it being made of glass, and it may be in the details of its construction of any of theusual forms.. At the upper end it is seated in a tubular socketpiece, G, there being a clamping-nut, g, and suitable packing, g', of any preferred character, to yfformV a `perfect union. The tubular socket-piece G communicates with a chamber, H, formed in a tube, H1', situated at an angle to the part G. The last-said part, H', lits snugly in the sleeve or chamber C, it being situated transversely across the line of the tubes B and D. It is provided at its outer end with a screw-thread, as shown at h, by which it there engages with a cap-nut, H2, having a havin also a tianve or cai h2 which closes tightly the outer end of the sleeve or chamber at C. The wallsof the part H are cut away,.

as shown at lr h4, to permit the passage through it of the valve-stem c. The partsV cut awa)v are long'euough to allow sutiicient play or oscillation of the part H', and therefore ot' the lower part of the gage-support.

The water-tube F is supported at the lower end in devices substantially similar to those above described-thatis to say, there ismat said lower end a tubular part, I, connected with the boiler by a screw-thread, i, a sleeve or cylinder, J, an outward tubular projection, K, a tubular socket, L,a tubular part, M, situated at an angle to the part L, slots m in the w'all thereof, a cap-nut, M, and a valve, N, and valve stein n, passing through said slots. This support at the lower part of the gagetube, it will also be seen, can rock through a large are on an axis transverse to that of the tubular parts I and K. With devices of this construction l am enabled to attach the watergage tube to the side ot' a boiler with greater ease and accuracy than are incident to devices for this purpose heretofore used.

lHeretofore it has been necessary to bring the upper and lower supports for lthe gagetube into line by rotating the tubular parts corresponding to those shown at B D and IK. This has necessitated much trouble and caused greatinconvenience. Mygage-supportisread-- ily adjustable to any angle of inclination at which it may be convenient or desirable to put the water-tube proper. I provide a universal joint or coupling with the boiler for the tube, both at the upper and the lower ends, so that it can be, as said, situated on any necessary line. The tubular parts B D and I K can be turned more'or less on their longitudinal axes, .and the parts G H' and L M can be turned more or less upon the axes of the parts H and M. This being true, it will be seen that the tube F can be readily arranged upon any desired line, and can be adjusted for any posi.- tion. -At the bottom of the support for the lower end an escape-cock, O, is provided, to allow the water to escape from the gage-tube when necessary. Preferably the threaded IOO parts b and t' on the tubular portions are conical or tapering, so as to engage tightly with the threaded apertures in the boiler.

What I claim isl. In a watergage fora steanbcngiue, the combination of a `gagetnlue, an attachment which communicates with the boiler below the water-line, an attachment which communicates with the boiler above said line, and devices at the ends of t-he gage-tube for connecting it to said attachments, which connecting" devices can be moved into dit't'erent angular positions relatively to theaxis ofthe attachments which communicate with the boiler, substantially as set forth.

2. The combination of an attachment comA municating with the boiler, the gage-tube, and a support for the end oi' the `gage-tube, which support com municatcs with the interior ot' said boiler attachment, and which can be moved relatively to the axis thereof', substantially as set forth.

3. The combination ot' a tubular attachment for the boiler, a tubular support for the end ot the gage-tube, and a. connecting-tube situated transversely to the axis of the tubewhichis connected with the boiler, and loosely connected with the last-said part, whereby it can be adjusted to different positions, substantially as set forth.

4. The combination of the gage-tube F, the tube B, communicating; with the interior ot" the boiler at the lower end of tube F, the tube I, communicating with the boiler at the upper end, and connecting devices between the watertube' and the tubes B and I, which hold the tube in a plane other than that ot' the tubes I and B, and which can be adjusted to dilierent positions relatively to the tubes I and B, substantially as set forth.

5. The combination ot' the water-tube, the tubes B and I, the sleeves or chambers carried by said tubes B and I, and the tubes which connect the tube F with tubes B and I, and which are mounted in the sleeves or chambers carried by the tubes B and l, substantially as set forth.

cate with the boiler, and provided with passages to allow the insertion of the valves, substantially as set forth. Y

8. The combination of the gage-tube, the.l

tube B, having the sleeve or cylindrical support @,and the devices which connect the gagetube with the tube B, having` the tube II fitted wit-hin the cylindrical support C and adapted to move therein, substantially as set forth.

9. The combination ot' the gage-tube, the tube B at the'end thereot, the sleeve or cylindrical support C, the interior ot' which conimunicatcs with the interior ot' the boiler, and the tube H', situated at an angle to the gage tube, and adapted to lit and to be moved in the sleeve or cylindrical support C, substantially as set forth.

1t). rIhe combination ot' the gage-tube, the cylindrical or tubular supports U and J, communicating with the interior ot' the boiler, and situated at an angle to the gagetube, and the tubes connected to the ends ofthe water-tube, and fitted within said cylindrical or tubular parts() and J, and adapted to be adjusted therein around the axis of said tubular support, substantially as set i'orth.

In testimony whereof l at'lx my signature in presence ot two witnesses.
